    What is Bi-Amping? It is the replacement of your speaker’s passive crossover, a source of audible distortion of your sound, with a precise Active Crossover placed ahead of your power amps. The power amplifiers drive the woofer and tweeter directly with no passive components getting in the way. The result is nothing short of breathtaking. You’ll hear detail and color in your music you’ve never heard before. The sound stage opens wide in all dimensions, and you can picture every instrument as if it was in the room with you.

    One of the most important specs for an active crossover is phase coherence. This is the alignment in time of the high and low outputs. If these are out of phase, sounds that are at or near the crossover frequency will be significantly distorted, because both the woofer and tweeter are both driving at this frequency, and if the channels are out of phase they will each be creating slightly different sound, which creates distortion. This video shows how precisely our channel phases are aligned:
